COVID-19 Vaccines: The Pfizer BioNTech, Moderna, and Johnson & Johnson COVID-19 vaccines are covered as part of CHPW’s medication benefit at any location they are offered.

As of 1/1/2023 Kroger Pharmacies will no longer be in the CHPW network. For a list of all pharmacies in our network, please click the Search Pharmacies button above.

Preferred Drug List (PDL)

On January 1, 2020, all managed care plans and Apple Health fee-for-service programs will continue to phase in a Single Preferred Drug List (PDL).

This change is mandated by the Washington State Legislature.

The Health Care Authority is working with managed care plans that serve Apple Health clients to create the Apple Health PDL. Managed-care plans will continue to use their own preferred drug lists for drugs not included in the Apple Health PDL.

Carved out drugs: Covered by Fee-for-Service

Prior Authorization

To request a prior authorization, step therapy, nonformulary, or quantity limit override, please call ESI at 1-844-605-8168, 24 hours a day, 7 days a week, and speak to a prior authorization service specialist. This specialist will review medical information and criteria with the provider or designee regarding the need for the requested drug.

Any pharmaceutical not listed on our formulary requires prior authorization. For self-administered drugs requiring prior authorization, please contact Express Scripts at 1-844-605-8168 or use to start the prior authorization process.

You can submit a request for a coverage determination review by sending in a Coverage Determination Request form or filling out the online form.

Pharmacy Reimbursement Issues

If you are having an issue with reimbursement, please call 1-800-922-1557 or submit an inquiry to ESI through their Pharmacist Resource Center.

Pharmacy Emergency Fills

Emergency fills may be covered to prevent interruptions in therapy during an emergency. View our policy on emergency fills.

Medications available for 90-day fills

CHPW covers 90-day supplies for most chronic medications. Ask your physician or pharmacist for a 90-day supply of your medications at your next visit.

OTC contraceptive billing

Apple Health (Medicaid) and CHPW cover over the counter (OTC) contraception, including most emergency contraception, with or without a prescription for clients. An adjudicated pharmacy claim is required for reimbursement.

To bill OTC contraceptives, pharmacies must follow the National Council for Prescription Drug Programs (NCPDP) standard and use the national drug code (NDC) or universal product code (UPC) found on the package.

A prescription for OTC contraceptives is not required. A pharmacy may use its NPI to process a claim when a prescription is not available.

Only products that are included in the CHPW’s pharmacy system database are covered. For a list of covered OTC birth control products, see the Apple Health covered OTC contraceptive list.

Emergency contraceptives are covered. There are no limits on age, quantity, or frequency.

For more information to help patients find the birth control that’s right for them, visit the Department of Health birth control and emergency contraception page.

For questions, contact [email protected] or email the HCA at [email protected].

Personal Medication Coach Program

The Personal Medication Coach Program works with doctors and patients to ensure that medications are effective and being used correctly.

The Personal Medication Coach Program is a service for members with multiple health conditions and who take multiple medications. This program is offered through a partnership between CHPW and MedWiseRx.

If you believe one of your patients would benefit from Personal Medication Coaching, ask them to visit the MedWiseRX website or call 1-844-866-3730 to get started.

Patient Review and Coordination Program

Our Patient Review and Coordination (PRC) Program helps members use their medical services safely and appropriately.

Members who are selected for PRC must choose one primary care provider, pharmacy, and hospital. One primary care provider makes sure medical care and prescriptions are coordinated for the health and safety of the member.

To refer a patient to the PRC program or learn more, call us at 1-866-907-1902.

Second Opinion Program

As mandated by the legislator in RCW 74.09.490, HCA has developed the second opinion program to improve prescribing practices in children.

In collaboration with The Pediatric Mental Health Advisory Group and the Drug Utilization Review Board, HCA has established pediatric mental health guidelines to identify children who may be at high risk due to off-label use of prescription medication, use of multiple medications, high medication dosage, or lack of coordination among multiple prescribing providers.

Partnership Access Line (PAL)

To assist prescribers in meeting the needs of children with a mental health diagnosis, and to minimize the need for required SON review, providers can contact the Partnership Access Line (PAL). PAL is a telephone based child mental health consultation system funded by the state legislature, being implemented in Washington State. PAL employs child psychiatrists, child psychologists, and social workers affiliated with Seattle Children’s Hospital to deliver consultation services. The PAL team is available to any primary care provider throughout Washington State.

PCPs may call 1‐866‐599‐7257 between 8am and 5pm for any type of mental health issue that arises with any child, not just CHPW members. For additional information on the PAL visit Seattle Children’s website.
